The book as a standalone is a great resource. Paired with the coursera course, it's a little redundant. I would say choose one over the other unless you are paying for the certificate. I enjoyed the book and felt like there were some great, high level ideas I can apply in business and in life. I just couldn't stand hearing it repeated at such a slow pace during the course. I actually sped it up to 2X the natural speed because I couldn't stand how slow he talks. He seems like a nice guy and knows his stuff, just talks to slow. So again, I give the book a five. I just think it drops in value if you are ALSO taking the course.
